The Charvel Model 3DR is a (super)strat guitar made in Japan in the eighties by the company Kyowa - Shokai under contract by IMC (International Music Corp). Grover Jackson chose a pointy headstock design that was popular among a new generation of guitar players. The Charvel Model 3DR differs from the Charvel Model 3 in that it has an HS pickup configuration with a Jackson J-80C humbucker and a slanted Jackson J-100S single coil. The neck was a Quarter-Sawn maple neck, with a compound radius 12"-16" maple finger board. The Charvel Model 3DR also features a reversed headstock and a slightly smaller "Dinky" body.
